Stuck with incline for awhile, I haven't flat benched in over a year. And only bench 135, focus on reps more then weight it'll build denser muscle.
Also use different grips. Ex. Close grip, wide grip, medium grip.

Your bench press is at a beginner weight, not a slam is what it is. if you work on it for 3-6 months youll be in a differnet place. Check out starting strength or stronglifts 5x5. You don't need to use complicated plans or 5/3/1 until your training stalls on a simple progressive loading plan. Working chest every 8th day is not enough. My training partner started out never benching and used 5x5 and he can rep 225 for 2-3 after ~8 months. He started with just the bar only to learn the technique. If you don't train in 3-5 reps you won't get used to recruiting the muscle for the kind of force you need for a max lift. Dips and triceps work will help get your numbers up.EDIT: I checked the charts actually your bench is better than my initial reaction. 185 bench at bw 165 is intermediate level.

That may be beginner weight but I'm not a beginner.. I clean 250 and squat 375. I just can't bench at all

Can you post a video of your bench pressing or dumbbell pressing. Preferable from a few different angles and using a weight corresponding to about your 6 RM. Sometimes it's minor tweaks in limb placement and setup that will make all the difference.

my chest lacks naturally as well, 8-10 reps with great form helped me alot. i did things like removed shoulders and arching my back out of the equation which let me lower the weight with better form and refuced any chance of rotater injury. i also focused on incline pressing movements and weighted dips..

That is a really good squat. Do you move good weight in overhead press and bent over rows/t-bar rows? I have a similar problem on bench. I get 4-5 reps at 250 but can't hit 280 w/o a spot. I stall around 2 inches off the chest. Do you have a spot in the lift where you stall out?

I am going to work on 2 sec pause at bottom and dead stop off 1 or 2 boards or off pins in power rack. Most of my chest work is in 5 rep or more range so I'm not specifically training my max with heavy triples like a power lifter would. i still like seeing my numbers go up.
